CERVANTES-VALENCIA, María Eugenia et al. Natural Antioxidants and their Effect Against Oxidative Stress Caused by Particulate Matter Pollution. Rev. Fac. Med. (Méx.) [online]. 2024, vol.67, n.4, pp.7-20.  Epub Oct 04, 2024. ISSN 2448-4865.  https://doi.org/10.22201/fm.24484865e.2024.67.4.02.

Environmental pollution can promote oxidative stress by exposing the body to various elements and substances that generate free radicals, such as lead and vanadium. These free radicals can negatively impact the respiratory, cardiovascular, immune, and neurological systems of vulnerable populations, including children, the elderly, and those with chronic diseases. To prevent or reduce oxidative stress, it is recommended to consume a balanced diet rich in natural antioxidants. These antioxidants can be found in various foods, especially in fruits and vegetables with intense colors, seeds, and spices. In recent decades, the effectiveness of consuming natural antioxidants such as resveratrol found in wine, coffee, curcumin, garlic, vitamin C, vitamin E, and green tea has been demonstrated. These antioxidants have beneficial effects on the body, including the protection of cell membranes, regulation of gene expression associated with inflammation, prevention or reduction of endothelial damage, and the decrease or diminished severity of neurodegeneration, liver, and pulmonary disorders. Additionally, they stimulate the immune response.

Keywords : Free radicals; ROS; RNS; antioxidants; oxidative stress.
